Line6 HX One Guitar Multi-effect

Compact Stereo Multi-Effects Pedal with Helix-Class Modeling

The Line 6 HX One White packs the HX Modeling engine from the Helix family into an ultra-compact stereo pedal. Behavioral modeling captures component-level quirks of notoriously hard-to-model analog circuits, including germanium fuzz and bucket-brigade analog delays. Stereo 1/4" I/O, USB-C, full-size MIDI DIN sockets and a TRS jack fit any rig.

What Sets the HX One Apart

The Flux Controller stores two parameter values for any chosen control and ramps between them at a user-defined speed when the footswitch is pressed — turning a single stomp into a slow swell, runaway feedback or a sudden snapshot change. A small OLED, three knobs and a category-based Effects Carousel keep navigation fast.

Effects Library and Processing Power

More than 250 effects from the Helix family cover drives, dynamics/EQ, modulation, delay, reverb, pitch/synth, wah/filter and a built-in looper.

• Effects Library: 250+ effects across distortion, dynamics/EQ, modulation, delay, pitch/filter and looper categories
• Modeling Technology: HX Modeling with behavioral component-level analysis — captures germanium fuzz, BBD analog delay
• Onboard Presets: 128 preset slots, editable via the free HX One Librarian app

Connections and Signal Routing

Stereo operation is built in, with four-cable-method routing for splitting drives into the amp front end and time-based effects into the effects loop.

• Audio I/O: Stereo 1/4" L/MONO + RIGHT inputs and outputs with four-cable-method routing
• MIDI: Full-size DIN MIDI In and Out/Thru — receives program change, CC and MIDI clock
• External Control: TRS jack for expression pedal or dual footswitch, auto-assigned to effect parameters

Power, Bypass Options and Construction

Power comes from the included 9V DC center-negative adapter at 500 mA, and most third-party pedalboard power supplies can drive it as well.

• Power: 9V DC, center-negative, 2.1 mm barrel, 500 mA — included adapter or third-party supplies
• Bypass Options: True bypass or buffered DSP bypass — DSP bypass required for delay/reverb trails
• Input Impedance: Adjustable input impedance — compensates for different pickup strengths
